Apple itself faced a similar challenge in 2005 when it announced it was switching to the Intel processors for its Macintosh computers. Apple was successful in moving its own ISVs over to the new architecture, and it has been one of only a few companies ever to survive a switch of platforms. Olds attributes Apple's success to the fact it kept in close contact with its of its ISV community, which was small to begin with.
Microsoft's task of getting its ISVs interested in porting their software to ARM will be an order of magnitude larger than Apple's. There are many more Windows software vendors that could supply software. "How do you get them to switch and get them to do it right?" Olds said.
That's the challenge that awaits Microsoft.
